摘要
提出了大气层外自旋稳定式动能拦截器的一种典型轨控发动机阵列布局。在分析小发动机工作的各种约束条件的基础上,推导了发动机推力角度、推力大小和冲量效率的计算公式,提出了发动机工作的控制方法。在各种初始条件下进行拦截仿真,所得的脱靶量均在0.3 m以内,可视为直接碰撞命中目标。同时通过仿真分析了冲量效率与自旋速度、发动机工作时间、每圈发动机个数的关系。
Put forward a type orbit-control engine array＇s arrangement of extra-atmospheric Spinstabilized Kinetic Kill Vehicle （KKV）. Analyzed small engine array＇s working conditions, discussed the account formula of engine＇s thrust angle, thrust size and impulse efficiency, advanced the control method for engine＇s working. Based on kinds of initial conditions, the simulation of the terminal guidance procedure was carried out. The miss distance quantities were less than 0. 3m, the results show that the interceptor could hit the target directly. Through the discussion and simulation, also analyzed the influence to impulse efficiency by spin rate, engine＇s working hours, engine＇s amount of each circle.
